it is within the province oi the disclosure to improve generally and toenhance the utilin disclosed mav be made within the scene of what isclaimed, without departing from the spirit of t 1e invention.

In the drawings Figure 1 shows in plan, a tool constructed in accordancewith the invention;

Figure 2 is a plan showing the opposite side or the tool from thatdisclosed in Figure 1 Figure 3 is an elevation wherein the tool isviewed edgewise;

Figure 1- is a section on the line 41-4- of F ignre l; I

Figures 5, 6, 7, and 8, are views illustrating the operation of thetool; and

Figure 9 is a section taken on the line 9-9 of Figure 8.

The tire tool forming the subject matter of this application comprises apair of levers 1 which are pivot-ally connected at 2 to form handles 3at the opposite extremity of the tool from the worhin ends 4; of thetool. The lever-s1. are provided on the? inner sides, attheir workingends 4 with reee.

shoulders 3 disposed approve. anitcly at right angles to the plane inwhich the levers open and. close. Thereces" 5 form ledges 7 disposedapproximately at right angles to the shoulders 6, the ledge beingextended longitudinally oi the levers. There are transverse openings orslots 8 which are extended entirely through the levers at the outer endsof the ledges 7, to form transverse lugs 9 at the ends of the levers.The inner surfaces of the lugs are rounded lengthwise of the tool, as

s 5 forming,

shown at 10. The levers are provided with transversely inclined surfaces11 located at the inner ends of the ledges 7.

One end of a rim is shown at 14. and the other-end ot' the rim appearsat 12, the ends 01 the rim having outstanding flanges 15;

Assuming that the ends 12 and 14; of the rim are in the overlappedrelation shown in Figure 5 of the drawings, the said overlapped ends areengaged. between the working ends l: of the levers, and thehandles 3 arepressed together. This lines up the ends the rim, an d the flanges onthe endld of the rim slide along the inclined surfaces 11 until they areon the ledges 7 and in lateral abutment with the shoulders 6, the lugs 9being at the extremity of the end 12 of the rim. The parts noware in theposition illustrated in Figure 6 of the drawing. The tool is swungcounterclockwise from the position of Figure 6 to the positionof Figure7 and finally to the position of Figure 8, the ends of the rim beingbrought into alinement, and the flanges 15 finally sliding through theopenings or slots 8, into abutment with each other.

The tool is simple, but is well adanted for carrying out an operationwhich. is often diilicult to pertterm, and, owing to its simplicity, thetool will withstand hard use.

lVhat is claimed is 1. A tool of the class described, comprising a pairof pivotally connected levers provided on the inner sides of theirworking ends with recesses formingshoulders disposed approxi mately atright angles to the plane in which the lovers open and close, andforming ledges disposed approximately at right angles to the shoulders,the ledges being extended longitudinally of the levers, there beingtransverse openings extended entirely through the levers at the outerends of the ledges and form- CHARLES A.
